I recently replaced the gearbox on my Whirlpool washing machine, a wtw5000dw1 due to some other obnoxious noises. The part number is W11035751 for reference.
There is play on the inner axel, maybe 1/8 of an inch moving through (not side to side). It's enough for the splutch assembly to not quite disengage which I believe is the cause of the sound.
Is the play usual? A manufacturing defect, a problem I caused installing?
